IVILLIAM CLARK, OF NEV YORK, N. Y.

ATTACHMENT FOB. PIANO-LEGS.

Specification of Letters Patent No. 14,948, dated May 27, 1856.

To all whom t may concern Be it known that I, IVILLIAM CLARK, of thecit-y, county, and State of New York, have invented, made, and appliedto use a new and useful Improvement in Means for Attaching Legs toPianos and other Articles; and I'do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawing, making part ofthis specification, wherein Figure l, is a vertical section of the atofthe leg and the bed of the piano or other article. Fig. 2, is anelevation of the metallic attachment for the bed, and Fig. 3, is asimilar elevation of the attachment for the leg.

Similar marks of reference indicate the same parts.

In attaching piano and similar legs, difficulty is experienced from twocauses; first getting the leg properly placed when prismatic or carved;second, the grain of the wood being endwise in the leg. Screws haveheretofore been made use of, but with carved and prismatic legs muchdifiiculty arises in making such legs' come to their correct place, andthey are very inconvenient and unsatisfactory, both in fitting as wellas in use; metallic connections have also been proposed, some tted withscrews entering the bed and legs, but liable to pull out, on account ofthe endwise grain of the wood; others with the metallic connectionsglued in.

My invention does not relate to any of the above mentioned devices, butconsists in the use of metallic connecting jaws attached tospectiveparts of the leg and bed by diagonal dowels and a chisel edgepenetrating the wood thereby preventing the metallic connections fromturning in their holes, and said dowels being glued into the woodeffectually secure the metallic connections so `they cannot becomedisconnected without breaking theleg or bed to which they are attached.

In the drawing A is a portion of the bed of a piano, table or otherarticle to which the leg B is to be attached.

C is the upper metallic connection in the bed A, and B is the lowerconnection in leg B. The bed A is to receive a hole of means, saiddiagonal holes passing into theA main hole. The end of the leg isperforated in a similar manner, and the connection I), entered anddriven down which forces a chisel edge d, formed on the end thereof intothe wood preventing the same from turning. The dowels b, I), are thenglued and driven into place and the recesses e, e, in the sides of theconnection D, permanently secure the same in place. The upper connectionC, is then attached to the connection D, by the tongue g, enteringbetween the jaws h, It, and a key E entered through mortises 1, 2, insaid tongue and jaws. The upper end of the leg B, is to be provided witha mortise or slot for admitting the key E. By setting the leg B onto thebed A, when in an inverted position, and entering the connection Cwithin the hole provided for it and turning the leg into the properposition, a slight blow will cause the connection C to remain in the bedA, when the key E, is pulled out and the leg removed. The connection Cis then driven home, the chisel edge c, preventing the same turning andon driving the glued dowels a, tightly into place the connection C ispermanently secured into the bed by the ends of said dowels taking therecesses f in the sides of said connection. It will thus be seen thatthe dowels a and Z), being of a suitable hard wood and binding into therecesses (e, f) on the sides of the metallic connection hold the same inthe iirmest possible manner and said connections cannot pull out withoutbreaking away all the wood between the diagonal dowels, and the metallicconnections themselves though not glued are prevented from turning ortwisting beneath the ends of the dowels by the chisel edges (c, (Z) ontheir ends or similar means. The dowels are also entirely hid from viewand do not enter the veneered surface of the case or leg, whereas ifsaid dowels were put in at right angles or nearly so with the leg, asthey have been in securing the nuts for bedstead screws and similarpurposes the said leg or case would be marred either in attaching theconnection or by the shrinkage of the endwise grained wood of the leg.

I do not claim metallic connections attached together by a key passingthrough mortises in the tongue and jaws, as these tions in the mannerand substantially as 10 themselves have before been used. specified.
